Found the thread where the RTT was flush mounted on the topper.

Flush Mounted Wedge RTT on GFC Topper?

Does anyone know if a wedge RTT can be flush mounted on the GFC topper? Instead of using beef racks, which raise the RTT off the topper, I’m thinking some custom side brackets that tie into the t-slots of each would work, as long as the RTT is the same width as the topper. The goal is to achieve the same look and form factor of a GFC platform camper but closer to the cab height. I’m willing to give up the floor pass-through. I really want a platform camper but my garage opening is 2" too short…
